The above wikis are all public wikis, but you can also create private wikis, that only select people can view.

I think web-based collaboration is going to get more and more important in the next few years, and even if you aren't interested enough in Local Government to justify contributing to this site, I believe getting the hang of wikis in general will be useful to you both personally & professionally. So give it a go - start a wiki today!

I guess the first question that needs to be answered is whether hosting your AMP on Wikidot is an option for Logan or whether you are constrained to hosting it on a wiki set up on Logan's servers? I can obviously give you a lot more help if you host it on Wikidot, and I think I can probably legitimately justify putting a reasonable bit of time in helping out, on the basis that learning how Logan approaches Asset Management would be of benefit to Bundaberg.

You can print directly from Wikidot to PDF, but the auto-generated PDF is a bit ordinary looking, so I think pasting into Word and cleaning it up is definitely the best option.

There are a couple of ways to use incorporate content from multiple pages into a single page in Wikidot. It complicates things a bit, but I found it to be the best way to combine the usefulness of a wiki with the constraints of an asset management plan.

Pros

Multiple people are able to edit different parts of the AMP at the same time.

Can hyperlink to other parts of the plan and supplementary information.

It is instantly up-to-date.

Cons

Getting people comfortable with the format can take a while.

Hosting it externally could be seen as a risk.

If you host it on Wikidot it will cost you about $50/ year if you don't want advertising.

If I was you I would set up a trial wiki and try to replicate the first few pages of your AMP on it. I am more than happy to help out.
